Description

  The present invention relates to a battery housing structure provided in a battery chamber of a digital camera, for example.

  In order to store a battery as a power source of the digital camera, a battery chamber is provided inside the camera. It is known that the battery chamber can accommodate either two cylindrical dry batteries or a pack-type dry battery in which two cylindrical dry batteries are integrally formed.

  The battery is accommodated in the battery chamber, for example, by being inserted in the longitudinal direction toward the bottom surface, and the insertion port is closed with a battery lid. Two contact pieces for contacting both terminals of the battery are provided on the bottom surface of the battery chamber and the battery lid, respectively. Here, the two contact pieces provided on the bottom surface are formed of an elastic member, the battery is pressed by this spring force, and the battery terminal facing the battery cover presses the two contact pieces provided on the battery cover. And contact is ensured.

  A cylindrical dry battery has a shorter length than a pack-type battery. Therefore, when a cylindrical battery is stored in the battery chamber, the contact of the contact piece of the battery lid and the terminal of the battery are easily separated, and a momentary disconnection or the like is likely to occur.

  Therefore, for example, it is conceivable that the contact piece is formed by a leaf spring, and the contact provided on the contact piece is largely separated from the bottom surface. However, if the contact is greatly separated from the bottom surface, the contact piece is easily deformed by an external load, and the durability of the contact piece is significantly reduced.

  Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to prevent the contact piece from receiving an external load or the like and causing a momentary interruption or the like.

  The battery storage structure according to the present invention includes a battery storage unit that stores a battery by being inserted from the insertion port toward the bottom surface, and is attached to the battery storage unit so as to be openable and closable. A battery cover that faces the end face of the battery, a support member that supports the battery cover so as to be relatively displaceable, and a contact portion that extends from the support member while being spaced apart from the battery cover, and that contacts the end face at the tip portion. An arm portion and a restriction portion fixed to the battery lid so as to straddle a part of the arm portion, and the battery lid is displaced in a first direction along the arm portion, so that the arm portion is The contact portion is pressed by the restricting portion, and the contact portion approaches the battery lid.

  It is preferable that the battery cover is displaced in a second direction opposite to the first direction, so that the arm part is released from pressing and the tip part is separated from the battery cover. The battery lid is preferably displaced in the first direction by the opening operation and displaced in the second direction by the closing operation. Further, the battery cover is preferably opened by sliding in the first direction and further rotating, and closed by rotating and further sliding in the second direction.

  It is preferable that the support member is rotatably supported by the battery storage unit. Moreover, it is preferable that an arm part and a contact part are formed as an integral leaf | plate spring. Furthermore, it is preferable that the rigidity of the support member is larger than the rigidity of the contact portion and the arm portion.

  The arm portion is preferably formed by a horizontal arm portion extending from the support member along the battery lid and an inclined arm portion extending from the horizontal arm portion while being separated from the battery lid.

  The battery storage structure according to the present invention includes a battery storage unit that stores a battery by inserting the battery from the insertion port toward the bottom surface, and a battery storage unit that is attached to the insertion port so as to be openable and closable. A battery lid that is closed and opposed to the end surface of the battery, an arm portion that is provided on the battery lid, protrudes from the battery lid toward the end surface, and the amount of protrusion of the battery lid can be changed. When the battery cover is changed from the closed state to the first protruding amount that causes the tip of the arm portion to abut the battery end surface, the arm portion is And a restricting means for restricting to a second protrusion amount shorter than the one protrusion amount.

  According to the present invention, the battery contact piece can be brought close to and separated from each other by causing the restriction portion to restrict the arm portion in accordance with the displacement of the battery lid.

  An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a battery storage unit.

  That is, as shown in FIG. 7, when the battery lid 30 is completely opened, the horizontal arm portion 343 and the inclined arm portion 345 are bent so as to approach the battery lid 30, and the contact portion 331 is attached to the battery lid 30. It can be approached.

  Note that the second battery contact piece 302 is similarly bent downward by the pressing portion 402 in the drawing, and the contact portion 332 is brought close to the battery lid 30.

  When the battery cover 30 is closed from the state shown in FIG. 7, the inclined arm part 345 is released from the pressing of the pressing part 401, the contact part 331 is separated from the battery cover 30, and the state shown in FIG. 6 is restored.

  As described above, in the present embodiment, when the battery lid 30 is opened and the battery lid 30 is displaced in the Y direction relative to the support member 32, the contact portion 331 of the battery contact piece approaches the battery lid 30. Accordingly, it is possible to effectively prevent deformation of the battery contact piece due to an external load when the battery cover is in an open state.

  That is, in the present embodiment, the amount of protrusion of the first and second arm portions 341 and 342 from the battery lid 30 is changed in conjunction with the opening / closing operation of the battery lid 30. When the battery cover 30 is closed, the protruding amounts of the first and second arm portions 341 and 342 are increased, thereby bringing the contact portions 331 and 332 into contact with the terminals (or end surfaces) of the battery. Can do. On the other hand, when the battery cover 30 is open, the amount of protrusion of the first and second arm portions 341 and 342 is reduced as compared to when the battery lid 30 is closed, and thereby the first and second arm portions 341 and 342 are not affected. External load can be prevented.

  A method of attaching the support member and the fitting member to the battery lid 30 will be described with reference to FIG. A notch 511 is provided on the side edge of the rectangular hole 311 of the support member 32 near the end in the Y direction. The shape of the notch 511 is substantially the same as the shape of the claw 355. Therefore, first, the support member 32 is engaged with the guide 31 so that the cutout portion 511 and the portion corresponding to the claw portion 355 of the recessed portion 41 coincide with each other when viewed from above. At this time, the locking claws 70 and 71 of the support member 32 are disposed on the locking protrusions 72 and 74, and the locking claws 70 and 71 are not engaged with the locking protrusions 72 and 74.

  Next, the fitting member 351 is disposed. That is, by inserting one claw portion 355 between the support member 32 and the recessed portion 41, the one claw portion 355 is disposed on the recessed portion 41 and the other claw portion 355 is recessed through the cutout portion 551. 41. The fitting member 352 is also arranged in the same manner.

  After the fitting member 351 is disposed, the support member 32 is strongly pressed in the Y direction. As a result, the locking claws 70, 71 are slid down from the locking projections 70, 71 and engaged with the locking projections 72, 74. Further, the two claw portions 355 are in contact with the facing surface 56 of the support member 35. As described above, the support member 32 and the fitting members 351 and 352 are attached. After the attachment, even if the battery cover 30 is pulled in the Y direction, the engagement claws 70 and 71 are engaged with the engagement protrusions 72 and 74. Therefore, the cutout portion 511 is not disposed on the upper side of the claw portion 355 and the fitting between the fitting member 355 and the recessed portion 41 is not released.
